Re: [Pharo-project] Memory usage
A few years back the interpreted virtual machine was fixed to allow an image to grow to the 4 GB limit. It is unclear to me if someone regressed the software to impose a 2GB limit again, or if the 2GB number mentioned is based on how things worked10 years ago?

Re: [Pharo-project] Memory usage
I'm sure I built a vm for 64 bits a few years back, maybe not a stack one, can't remember ya http://lists.squeakfoundation.org/pipermail/vm-dev/2010-January/003732.html On Tue, Jul 31, 2012 at 11:01 AM, David T.

It would certainly be possible to do it, but I don't think that anyone has tried.

I expect that Eliot would want to put his energy into the new object memory format(s), so a StackVM for the current 64-bit object memory would probably require someone to volunteer to do some development work.

Lewis le...@mail.msen.com Hi Jannik, I am not a Mac user, and I have only ever done this on Linux, so I cannot promise that it will be easy. Possibly Esteban can give us some advice here, and correct my errors. Also, if you are going to try this, we may want to take the discussion to the vm-dev list. You will need to install the Mac tools for compiling Unix programs (sorry I do not know what this is called) and you will need to be able to compile programs using CMake and the gcc tools on a Mac. I know very little about this myself, but I'm sure others can give some tips. The actual VM that you will need to build will be an interpreter VM, and you will be building it with a preprocessor macro set to force use of the 64-bit object format. The resulting VM will be slow compared to what you are used to with Cog, and it may not have all the features that you would expect from a Mac VM (i.e. the VM that Esteban supports), but I expect that it should work on Mac and that it would allow you to run a 64-bit image prepared with the SystemTracer. As luck would have it, Ian Piumarta is in the process of updating the unix VM code right now, and this will make it easier to do the build for 64-bit images. I would say that we should wait a couple of days before starting any new work on this so that we have all of the latest updates. I'm not sure if this is something that you want to get into, and it is not what I would call easy ;) But if you want to try it I will do my best to step you through the process.

Hi Jannik, The system tracer is explained in the class comment of class SystemTracer. The comment was written by Dan Ingalls (I think), and gives credit to Ted Kaehler as the inventor of the original. Class SystemTracer2 has additional documentation including how to run the trace. SystemTracer2 is a newer version that you will actually be using, so you can think of SystemTracer as the original reference implementation, while SystemTracer2 and its subclasses are variations on the original. SystemTracer64 is the subclass that implements conversion logic for copying 32-bit objects into the experimental 64-bit object memory format. This object format is described in the SystemTracer64 class comment, and more information is available at http://squeakvm.org/squeak64. A system tracer will first put your image into a quiet mode, then copy and convert the running object memory to a new image file, and then wake up and return to normal. This is similar to saving your image and restarting from a disk file, except that the system tracer will trace your object memory to a new format rather than saving it unchanged. To trace your running image to a new 64-bit image file, you would do this: SystemTracer64 writeImage:
Re: [Pharo-project] GZipWriteStream crashing my VM when serializing ?

Re: [Pharo-project] Pharo for iOS
Well this is an old note, but I thought I'd answer it. You can download, install and run the Scratch.app https://github.com/johnmci/Scratch.app.for.iOS This is not the closure VM, but does have the Open/GL canvas, or you can choose to use the alternate canvas which is based on CALayers. Now about building apps on iOS. You can choose to either (a) run the VM and show the squeak desktop which I did for Blob and Swirl, these being experimental early toys mostly to track the stability of the VM as Apple sends developers crash reports if there are enough generated. (b) run the VM and show a Cocoa UI, do all work via Smalltalk, Both the Fractions Calculators and WIkiServers do that. This is hard because getting a walk back means setting up VNC so you can control things, and using proxy and callbacks to do work in Smalltalk code is hard to debug and code, plus you need to pass in all these constants to Alien or FFI which you gleam from the apple header files. Bad things happen when you deadlock between the VM and iOS callbacks. (c) run a cocoa app and use the VM as a subprocess to be the Model, where the View and Controller is all Objective-C. Which is mostly how the Scratch.app is designed. We give taps, keyboard, load this project, and stop/go to the VM as a result of interacting with cocoa controls. The VM in turn mostly provides audio and frame updates. Oh and Im not sure about the JIT stuff, pre 3.2 making a virtual memory page executable was not allowed by non-root apps. But in post 3.2 it seems they added some extra mmap keywords #define PROT_EXEC 0x04 /* [MC2] pages can be executed */ #define MAP_JIT 0x0800 /* Allocate a region that will be used for JIT purposes */ Obviously someone could try it...

Re: [Pharo-project] Pharo on Apple App Store
I'm not sure anyone really answered the question. (a) Yes you can build squeak/pharo VM based applications for the iOS platform and distribute in the App Store. This assumes you adhere to the rules. (b) Yes you can build Squeak/pharo VM based applications for the OS-X platform and distribute in the OS-X App Store. This assumes someone wants to take the time to port the file dialog logic from Sophie to Pharo since you will be rejected if you present a Squeak file open/save dialog. Lastly you can't download MC packages to the app for doing on the fly updates, any updates have to go thru the app store. An example of alternate technology is Sparkle and Apple has rejected apps that use that technology to provide an update path. PS No I can't say I've actually attempted getting a squeak based app into the OS-X store, perhaps this summer, still that is my tea leaf reading of the situation.

[Pharo-project] code coverage?
Ok as I'm testing this new VM Im wondering has anyone done a code coverage review of the Pharo image in relationship to the suite of available tests? I wondering how much of the image side code is actually used? Part of the problem here in cross checking the list of internal plugins is that I need test cases to actually exploit the plugin code so that I can confirm it works, even to confirm it gets called. No doubt from the other side it would be interesting to see from a VM platform perspective if the Smalltalk Sunits actually execute a reasonable set of the slang/objective-c/C code. -- === John M.

Re: [Pharo-project] Hashed collection changes, the performance graphs
I looked at the squeak identityHash in squeak a few years back (a) how efficient was the algorithm? Attempted at one time to replace with a fixed array of numbers. There was some benefit on slow machines. (b) only calculate the identity hash when required, but then how do you mark the oops with that fact when all the identityHash values are in use in the image. The hassle of fixing an image to use the new hash logic wasn't worth the gain which was difficult to measure. In both cases I was more interested in the cpu usage on those 68K machines.

While there are uses for systems that are smart enough to give exact answers, most computation happens in a world of tolerances, with numbers that are not cherry picked for aesthetics. As somebody else (Sig perhaps) said, the behavior of the base system magnitude classes should not change when a different package is loaded. #asComplex is the gateway through which one can tell the system that complex numbers are expected and desired. The more you write, the more it becomes clear that there also would need to be a #asComplexSymbolic or something to invoke behavior one might expect from Maple and other symbolic systems. I strongly recommend starting with a numerical approach to a closed system of complex numbers. GSL provides much of what should be available, and can be mapped into Pharo by FFI/Alien. The result would get used. If you then want to compete with Maple and Mathematica, that really should be done separately. For examle, there are times when I use logs to estimate the number of digits required to hold a number, and if the argument is negative, I goofed and expect an error. Bill, My apologies for mixing a personal philosophy discussion into the Complex header.

There are alternatives, and they are discussed in this fairly extensive thread. Besides, someone wanting complex numbers will look for and load a package to support them, as long as it is good code. Complex is fine as far as it goes; some FFI magic to benefit from GSL functionality would be nice. We should also have an analog to FloatArray that has complex entries; again, a wrapper onto GSL would be a nice addition. I have no power over Ken; he can build what he wants.

I needed the MD5, SHA1 and SHA256 classes. I renamed them to CFMD5, CFSHA1 and CFSHA256, I also prefixed all the methods in the required class extensions with cf. For example ThirtyTwoBitRegistercfBitShift: anInteger. You can use a simular approach for Glorp. Jan. PS: Another dependency of Cloudfork is a HTTP client. I'm now playing around with the CurlPlugin, this plugin works very well. Things like supporting https become real easy 2009/5/22 Mariano Martinez Peck marianop...@gmail.com On Fri, May 22, 2009 at 9:18 AM, Ramiro Diaz Trepat ramiro.diaz.tre...@jpmorgan.com wrote: I'm really sorry to hear it is no longer being maintained. It was a necessary package to connect to properly set up Postgres databases, that requiere sending password hashes with SHA-1. We will probably face this kind of need when interacting with the outside world in general. Yes. That's why I saw it. I am trying to make Glorp to work in Pharo, but as you know Glorp in Squeak only works with Postgres. And the native postgres driver requieres cryptography package when you use md5 :( Just for now, I disable md5 from my postgres and use password auth- method. With this, cryptography is not needed. However, this is not an option in a production enviorment. Cheers, Mariano It was a fantastic package, I wonder why the maintainers droped

For the psuedocontext I think you should check with Eliot I though he said that class was no longer needed?

Re: [Pharo-project] Unicode test II
-61 mmm 0xFFC3 ? int utf32Code; /* UTF-32 unicode value */ does anyone consider the data coming back could be a 32bit value that is unsigned? value = positive32BitIntegerFor(value); oh details details... oh wait look we ask if the value is an integervalue, aka a SmallInteger, if it is then we pass it up, if it's not a SmallInteger, thus a Large Integer, we decide to pass it up as a Positive 32bit value. Ergo if the value was 0xFFC3 why then it would flow up as a negative SmallIInteger, like -61, then twist the mind of Michael?

[Pharo-project] mac menus in Pharo
I'm wondering if there is any interest in having mac menus in Pharo. This was done for Sophie and Scratch, and attempted for 3.10. I could drag the required change sets out of storage to implement the proper file/edit menu in Pharo and have it respond to cmd-Q etc if there is any interest... -- === John M.

By the way,
what is the recommended VM?
For now, I use the Squeak 3.8.18beta1U vm. I don't even know if there is a
newer one...
That would be the 3.8.18beta4U vm
3.8.18b4Use NANO-SLEEP logic to ensure sleep is accurate to
millisecond, no-usage which is more CPU friendly
would give upwards of 10ms error to delays which is
unacceptable.
Fix issue with arguments passed as parms to the VM, the
parm number
(2) was treated as being
special by the carbon vm for historical reasons, but in
fact it was
not actually set. Try to follow the
generic unix rules instead.
3.8.18b3Compile with xcode 2.5.x on powerpc machine os-x 10.4.x
set utf832code field to zero on fake wheel event
up/down/left/right arrows
print more diagnostic data on failure to allocation
virtual memory
on browser plugin setup
3.8.18b2The Sophie team noticed that
InternetConfiguration
getMacintoshFileTypeAndCreatorFrom: 'test.jpg'
This returns byte reversed data on macintel #('GEPJ'
'elgo')
sqMacInternetConfiguration.c use CFSwapInt32BigToHost
swap OSType
